Detect multiple boundary curve

I’m loading a series of curve with “Geometry Pipeline” and for each sub-series of curve I would like to detect their curve boundary
Any idea?

Hi Japhy,
I was looking to extract only the overall boundary curve without the inside

Try to sort the curve groups by area and get the largest…

Depending on what is going on inside the containment area might work better, length in this case will work.


Thanks a lot Japhy for your help!
